Stamp vocabulary v1 (carve ellipsoid/arch, fill pillar/dais) with smooth CSG and seeded relief; the
director resolves records (stable ID, strate, micrometre position, conservative bounds) from
hash(seed, strate, ID) with up to 512 candidates and rejects any that touch a passage mouth, walk corridor,
content face or ceiling/bedrock band; a stamp BVH skips tiles outside all bounds. No requests: canonical
JSON and owner hashes unchanged. --landmark-chamber-demo adds a SW chamber (buried; see review).
fast/medium/full PASS on clean builds. Research R10 (read-only): ore/resource channel design.
Review also records a pre-existing W1/W12 determinism mismatch at a non-spawn camera (L37+, not S14).

ResolvedLayoutSnapshotV3::finalize maps each strate's generator and interface once into capability
records (FI gradient air-gap, surface/FI landing support, passage-anchor columns, SW-to-TN floor);
ApplyResolvedStrateBoundaryBand and passage composition read those instead of generator kinds. Derived
records stay out of canonical JSON, so layout identity is unchanged. Owner hashes identical to L41;
fast/medium/full PASS on clean Clang and GCC builds; cost within noise.

The passage mouth fade multiplied the signed carve distance by zero, which turned native rock into an
open surface (the reason earlier rounds stamped walk pads at mouths); it now blends between the
uncarved field and the full signed carve. The FI style-0 route followed a lifted grade envelope over
the crater (the "bridge"); it now runs on the rim and follows the native surface. New built-shape and
crease audits with thresholds frozen before the fix (L36 and box controls fail). 24/24 passage rows,
30/30 determinism, 16/16 invariants, 18/18 interface/ring. Unreal: one recipe setter (uncompiled).
Research R1 (read-only, web): ranked proposals for natural walkable mouths, floor-limited carve first.

The shared passage carve took the minimum of piecewise-linear capsules (scallops at joins) and added
wall relief on regular 8 m / 4 m octaves, which read as evenly spaced ribs. Interior sweep joins are
now Catmull-Rom smoothed and the relief uses irregular rotated 43/29/19 m scales; the natural wobble
remains. New axial ripple audit (0.125 m radius samples, 0.5-8 m periods): beaded control and L34
geometry fail, all 24 passage rows pass. FI mouth tread apron tapered. 30/30 determinism, 16/16
invariants, ring audits LOD0-8 pass; cost within noise.

Route planning for an upper SurfaceWorld failed on long candidate chords over steep relief; chords
are now capped to the arrival/departure radii on an 8 m centre grid with an origin-proximity cost
(21.5 m walk, about 4 deg). The departure passage starts at the SW ground and tunnels down through rock.
FI -> SW -> TN fixture: all 4 styles pass every passage audit on both compilers. FloorProfileBlend
now checks endpoint height/tangent seams (step and tangent-step negative controls detected). Owner
world hashes unchanged; 30/30 determinism; cost within noise.

Band faces now use signed distance to the displaced solid intervals, continuous across bands, so
MC interpolates the interface instead of terracing at density levels. The Gradient amplitude is
restored to width/8 (about 4 m peak-to-peak at 16 m). Ring/terrace audit at LOD0-8 on the FI floor and SW
ceiling passes; negative controls: L30 (rings) and L31 (flat) both fail. Hole/interface audits,
16 passage rows and 24/24 determinism pass. Evaluator 20. Cost vs L31 SW +1.9%, FI +1.5%.

On the real FloatingIslands recipe, column caps sit inside anchor-island rock and native bedrock;
the old check sampled the route foot. The audit now samples each planned cap against the native
field (negative control: a cap moved into air is detected). The audit runner records requested vs
actual recipe and exits on mismatch. All 16 passage rows (4 styles x 2 recipes x 2 compilers) pass.
The readable shader uses a smooth tint. Interim: FI Gradient displacement capped at width/256
(flat floor, no contour rings); restoring real undulation is L32. Evaluator 19.

EVoxelStrateTransition from the upper strate shapes the bedrock(N)/ceiling(N+1) interface in the
shared composition layer: Hard flat; Gradient = smooth 2D hash surface (16 m owner width, about 4 m
measured undulation); Interleaved = 3D domain-warped fingered overlap within the width. Each band
keeps >= 2 Core voxels solid; faces return to the seam near passage mouths. Interface audit over
512 m: 0 hole columns for all modes; wider-than-declared and too-thin controls rejected. All passage,
route, proof and validator audits pass; deterministic Clang = GCC. Evaluator 15. Cost +4% SW,
+1.3% FI vs L28. Open: ring-like artifact on the FI floor capture; transition look unverified.

Fixes the L24 ribbon (owner request). NOT merged: the open-air support gate leaves ~4,000 unsupported
samples on every SurfaceWorld-recipe passage style (TN -> SW), a walkability regression. L26 fixes that
on this branch. See Linux25/REPORT.md.

Core plans inter-strate passages from each upper strate's FStratePassageConfig for every
generator: Straight / Worm (the new natural default: meander, variable radius, rough walls) /
Spiral / Cascading. A naturalness audit (no >8 m flat runs, >=0.20 m wall relief) fails on L23's
smooth tube. FloatingIslands selects Spiral, with a deterministic unique anchor island (ordinal 2)
joined to the bedrock floor by a rock root. The SW arrival no longer stamps flat shelves.
Capsule audits 0 blocked / 0 unsupported / 0 grade failures, all styles. Full-view hashes
deterministic W1/W8/W12, Clang = GCC (reviewer re-run). Evaluator 10, FI geometry 5.
KNOWN: the FI helix renders as a spiral ribbon in open air around the pillar instead of a tunnel
enclosed in rock; fix next round. Unreal edits uncompiled.

After L22 the FI -> SW passage no longer connected the strates (legacy owner-voxel coordinates,
lower end 23 m above SW), and Core never carved passages through the bands. Now the director
plans passages from the resolved layout (PlanResolvedLayoutPassagesV1; deterministic hash of
seed/strates/connection; placement disk from PassageConfig, 8-24 m around (0,0)); shared
composition applies generator field -> bands -> bounded passage carve and support shelf, opening
the bands only along the tunnel. Mouths bind to the strate routes. Capsule audit: 0 blocked /
0 unsupported (325,962 samples FI, 284,319 TunnelNetwork), negative controls detected; all 8
generator kinds exercised. SW away from the passage is bit-identical. Layout V3, evaluator 9.
Open: look not yet natural (stepped tube in FI void, terraced SW arrival); SW-as-upper route
planning fails; Unreal adapter uncompiled.

StrateLayoutChunkSizeMeters (world setting, default 8 m; owner decision) is resolved once in
the director/adapter and standalone loader; every generator reads the resolved width (no
CHUNK_SIZE / Core-tile inference). Every strate gets solid ceiling and bedrock bands from its
BoundarySealThickness in the shared composition path (diggable by default); faces come from the
shared boundary path. Owner world: FloatingIslands +8..-120 m (128 m, now with a bedrock floor),
SurfaceWorld -120..-632 m (unchanged; full-detail and exact-query hashes equal L21); the 60 m gap is
gone. The strict layout validator passes on the real world, with 0 endpoint dispatch
disagreements. Spawn/benchmark camera derived from route.front. Ledges under the islands gone
(reviewer capture). Evaluator 7, recipe schema 2, layout snapshot 2, FI geometry 4.
Open: SW cap profiles exceed the ceiling band (owner call); transitions still Hard; Unreal
setting/manager/adapter edits uncompiled here.

Core ResolvedLayoutSnapshotV1 (canonical JSON, stable identity): per strate stable ID, generator,
recipe, interior bounds in metres, ceiling/bedrock bands as Core really applies them, transition
mode/width, dispatch provenance. Validator: compat mode reports today's deviations; strict mode
enforces ceiling -> content -> bedrock -> next ceiling (owner rule), two separate bands, nominal
contiguity, interpenetration only within the declared EVoxelStrateTransition width; 7 negative
controls rejected. Findings: SW built at -120..-632 m although the params say -60 m; a 60 m unowned
gap filled by analytic FI fallback; no active bedrock bands; transitions ignored by Core.
All L19 hashes unchanged (28 + 14 crossing runs). The Unreal adapter exports resolved_layout
(uncompiled here).
